PT-141 (Bremelanotide) is a Melanocortin receptor agonist researched for increased sexual desire in premenopausal women, improved sexual arousal, non-hormonal sexual enhancement. Common dosages range from 1.75 mg per dose (FDA-approved) administered on-demand, 45 minutes before anticipated activity; maximum 8 doses per month. Below are the most frequently asked questions.

Frequently Asked Questions About PT-141

What is PT-141?

PT-141 (Bremelanotide) is a Melanocortin receptor agonist. Synthetic α-MSH analog targeting MC1R and MC4R for sexual desire modulation. It is researched for increased sexual desire in premenopausal women, improved sexual arousal, non-hormonal sexual enhancement.

What is the recommended PT-141 dosage?

Common dosages range from 1.75 mg per dose (FDA-approved), administered on-demand, 45 minutes before anticipated activity; maximum 8 doses per month via subcutaneous self-injection. Cycles typically run on-demand acute dosing; no continuous cycle required.

What are the side effects of PT-141?

Nausea (40% incidence, especially first injection), flushing (20%), injection site reactions (13%), headache (11%). Transient blood pressure increases (2-3 mmHg average). Contraindicated in uncontrolled hypertension.

Is PT-141 legal?

FDA-approved (2019) as Vyleesi for hypoactive sexual desire disorder in premenopausal women. Prescription medication. Off-label use for males by some providers.

What is the half-life of PT-141?

The half-life of PT-141 is peak effects 15-30 minutes post-injection, which determines the on-demand, 45 minutes before anticipated activity; maximum 8 doses per month dosing schedule.

How do you reconstitute PT-141?

Add bacteriostatic water to the lyophilized PT-141 vial. Let the water run down the side — never spray on the powder. Swirl gently. Use our peptide calculator for exact amounts.

Can you stack PT-141 with other peptides?

Works through a unique mechanism distinct from PDE5 inhibitors; not typically combined with other sexual enhancement agents.

Where can you buy PT-141?

PT-141 is available as a research chemical from vetted suppliers with third-party COA testing.

How long does it take PT-141 to work?

Initial effects may be noticed within 1-2 weeks, with more significant results typically appearing by weeks 4-8 of a on-demand acute dosing; no continuous cycle required cycle.

What makes PT-141 unique?

One of the few FDA-approved peptide therapies and the only medication targeting sexual desire through melanocortin brain pathways rather than vascular mechanisms — treats desire itself, not just physical function.
